OEM Auto Parts from Turkey — Bursa TOSAB and the European Supply Chain

Turkey is Europe's top bus and light commercial vehicle producer and the continent's 4th largest automotive manufacturer overall, exporting $37.2 billion worth of vehicles and parts in 2024. The automotive sector has been Turkey's export champion for 18 of the past 19 years, accounting for roughly 17% of the country's total goods exports.

Turkey's auto parts manufacturing market reached $9.31 billion in 2025 and is projected to grow at 6.20% CAGR through 2035. Behind the vehicle assembly lines sits a massive Tier 1, Tier 2, and Tier 3 supplier ecosystem producing components that end up in vehicles driven across Europe, the USA, Latin America, and Africa — often without buyers knowing the parts were made in Turkey.

Trade Istanbul Hub connects international wholesale buyers with verified Turkish auto parts manufacturers across every major component category — for passenger cars, light commercial vehicles, and heavy trucks.

Manufacturing Geography

Bursa — TOSAB & OEM Cluster

Bursa is Turkey's automotive capital. The city hosts Toyota, Renault (OYAK-Renault), Fiat (TOFAŞ), and Robert Bosch production operations alongside hundreds of Tier 1 and Tier 2 suppliers concentrated in the TOSAB (Tüm Sanayiciler ve İş İnsanları Derneği Bursa) cluster. The largest centres for auto components production are the Kocaeli region with the TOSB specialised industrial zone, and Bursa where the Robert Bosch plant is located. Global companies operating in Turkey's auto parts sector include Robert Bosch, ZF Friedrichshafen, Mahle, Continental, Valeo, Michelin, Denso, Autoliv, Magneti Marelli, and Pirelli.

Kocaeli & Sakarya

The Kocaeli-Sakarya corridor is Turkey's second major automotive manufacturing region. Ford Otosan operates a major production facility here producing Transit vans and commercial vehicles for European markets. The region's Tier 2 and Tier 3 suppliers produce stamped body components, plastic interior parts, rubber seals, and electrical harnesses.

Istanbul

Istanbul hosts Mercedes-Benz Türk bus and truck production at its Hoşdere facility alongside hundreds of aftermarket parts distributors and smaller OEM component manufacturers serving domestic and export markets.

İzmir & Manisa

İzmir's automotive supplier base focuses on rubber components, plastic parts, and electronic modules. Manisa adds electrical components alongside its white goods manufacturing.

Trade

Agricultural & Construction Equipment Parts — Turkey exported $173 million worth of tractors to the USA in 2024 alone. Tractor and construction equipment components — hydraulic cylinders, PTO shafts, implement hitches, and cab assemblies — are a growing export category to Africa, Latin America, and the USA.

Growing Markets — Latin America, Africa & USA

Turkey's main auto parts export markets include Germany, France, Italy, UK, Romania, the USA, Spain, Belgium, and Poland. The main product groups are engine parts, gearboxes, rubber components, wheels and wheel components, brake systems, and clutches.

Beyond established European markets, Turkish auto parts are making significant inroads into Latin America — Brazil, Mexico, Colombia, Argentina, and Chile — where vehicle fleets serviced by aftermarket parts represent a massive and underserved market. Turkish ECE-certified brake components, filters, and suspension parts are price-competitive versus Chinese alternatives while offering certification documentation that Chinese manufacturers often cannot provide.

In Africa — particularly Nigeria, South Africa, Kenya, and Egypt — Turkish aftermarket parts are growing rapidly as vehicle import volumes increase and local distributors seek reliable supply chains. Turkish manufacturers offer Halal-compliant documentation, Arabic-language packaging options, and logistics routing through Istanbul's ports that minimises transit time to African destinations.
